Continuing to support this?

Hi Aaron,

Lots of devs have been forking and changing this gem to keep it alive, yet your master branch is still on DM1.0.  I've been using someone's fork and wanted to modify the slug update algorithm.  After my changes, at least the unit tests run and pass via "spec ./spec/integration/slug_spec.rb".

Submitting my fork because at least it works.  Are you going to continue supporting this gem?

Thanks,
David
